Based on findings for nanoporous gold, supplemented by the Gibson–Ashby scaling law for Eeff, we argue that both functions are quadratic in bending-dominated structures. We present finite-element-modeling results for Eeff of coarsened microstructures, in which g and φ are decoupled. These results support the quadratic forms.en2352-43162024Elsevierhttps://creativecommons.org/licenses/by/4.0/ElasticityFinite-element modelingNanoporous goldNetwork materialsScaling lawsTopological genusEngineering and Applied OperationsPhysicsJournal Article10.15480/882.950710.1016/j.eml.2024.10214710.15480/882.9507Journal Article
